Preface to Mechanical Design Engineering Handbook

This edition of the Mechanical Design Engineering Handbook has been extensively updated. Each chapter has been reviewed and developed.

Chapters 1 and 2dealing with the design process and specification have been updated with the development of the total design process and an introduction to project management.

Chapter 3 has been revised substantially incorporating developments in creativity and ideation processes relevant to engineering.

Chapter 4 has been further developed to illustrate the scope and context of machine elements.

Chapters 5 and 6 introducing the first of the machine elements to be considered in detail, bearings, have been expanded to include flow charts illustrating the design of boundary lubricated, hydrodynamic, and ball bearings.

The introductory and extended worked examples have been retained throughout the chapters on machine elements in the book to enable the reader to follow the detailed analysis and associated design decisions.

Chapter 7 addressing shaft design has been expanded to include consideration of a factor of safety according to the DE Goodman, DE Gerber, DE ASME elliptic, and DE Soderberg criteria.

Chapters 8–11 introducing gears have been expanded to include flow charts for the selection of spur gears, and the calculation of bending and contact stresses, and the design of gear sets using the AGMA equations.

Similarly, Chapter 13 introducing belt and chain drives has been extended with flow charts for the selection and design of wedge and synchronous belts, and roller chain drives.

Chapter 14 on seals has been updated to include additional examples. Chapter 15 has been extended to include selection and design flow charts for helical compression spring and helical extension spring design.

Chapters 16–18 have been extended with additional examples of the various fastener, wire rope, and pneumatic and hydraulic technologies, respectively.

Three short case studies have been included in Chapter 19 illustrates the importance of a detailed consideration of tolerancing in precision engineering.

Chapter 20 is a new chapter providing an overview of a diverse range of machine elements as building blocks for mechanism design. Throughout the text, an additional 100 or so images have been included in order to aid the reader in becoming familiar with the technology being considered.

Mechanical engineering design is an engaging subject area with many applications and this major revision has been a pleasurable undertaking enabling the implementation of many updates from my engineering and design practice and associated interactions.

I hope this text is able to aid the reader in the development of the understanding of the principles and associated technology and in its implementation in worthwhile innovations and applications.


I have the delight of having developed and practiced my design and engineering skills and their application with so many impressive individuals and organizations.

I would like to thank my colleagues at Imperial College London and Q-Bot Ltd, and former colleagues from the University of Sussex for their extensive support and patience through the years.

Without the chance to practice engineering and design on exciting and ambitious commercial applications and research projects, the opportunity to develop knowledge is limited.

I have had the privilege of working with diverse companies and organizations including Rolls-Royce plc, Alstom, Snecma, DaimlerChrysler, BMW, MTU, Volvo, Johnson Matthey, Siemens, Industriales Turbines Propulsores, Fiat Avio, Airbus, Ricardo Consulting Engineers, Ford, Rio Tinto

McLaren, Dyson, Naked Energy and Q-Bot Ltd, Innovate the UK, the EPSRC, and Horizon 2020. I would like to thank the engineers, designers, and managers from these companies and organizations for the opportunity to engage in such exciting technologies.

Several colleagues, in particular, have been very helpful in the implementation of this edition including Shayan Sharifi and Andy Brand who assisted with proofreading, Ben Cobley, and Ruth Carter who assisted with several of the images.

Many collaborators and companies have kindly given permission to include key images to aid in the effective presentation of this book and this is gratefully acknowledged.

Finally, I would like to thank my wife Caroline for her patience over the last year when I have expended a significant number of hours working on this project.
